We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.

Cotton Candy and Wind

What does cotton candy have to do with winds? In the center of the machine, sugar is melted in a spinning drum. As the machine spins, the rotation leads to apparent forces on the solution that makes it "fly out" from the center. It's the spin that's important - no spin, no cotton candy. In a similar vein, the spin of the earth leads to the complex patterns of winds that we see on the globe.
